Runs "qmake" to regenerate the Makefile, if necessary, then "make" to
rebuild mountmon.

Usage: rebuild [-cnqrx] [--clean|--nuke-first|--qmake-anyway|--release]

  -c,     --clean          Run "make distclean" before running "make".
  -n, -x, --nuke-first     Delete and recreate the build directory before
                             running "make".
  -q,     --qmake-anyway   Run "qmake" even if timestamps suggest it
                             shouldn't be necessary.
  -r,     --release        Perform a release build instead of a debug
                             build.
